Betrayal. Jill Andersen, #5

Someone is killing Baltimore's heroes. The ones with badges. The ones who put out fires. The ones who debate laws designed to make the citizens' lives better. None of them are safe, and their deaths amount to little more than public spectacle. A mysterious band of militants called The Collective takes credit for the killings, but the origins and identities of its members are unknown. Jill Andersen now has an FBI badge on her hip.
She is tasked with bringing down the cult, and she must make sure she doesn't wind up in their crosshairs in the process. All of her theories and leads come up empty - none of the usual suspects are behind these ghastly murders. They might just be in the line of fire themselves. With those closest to her now targets, Jill must race against the clock to determine who's killing the best Baltimore has to offer.
But along the way, she'll discover a jarring secret - one that threatens to make her question everything that has happened in her life to this point. Assuming it doesn't kill her first. Betrayal, the gripping, hard-hitting fifth novel in the Jill Andersen mystery series (Bounty, Blood Ties, Behind the Badge, Behind the Mask), gives readers yet another taste of author J. D. Cunegan's comic book-inspired brand of fast-paced prose, with chapters that fly by and plot twists that will leave readers guessing and waiting for more.
